I think it only works for Kanji, but it wont work for vocab words ever.
If youre looking for something to give you that second change, just Install the WK override script. But make sure not to abuse it!
Also, I just wanna point out that giving the wrong yomi reading isnt really a “Pretty trivial thing”. WK works on making sure you know the deference between those readings and what they’re used for. Its a very large part of the platform, but obviously mistakes will be made so no need to be super hard on yourself, but it is very much worth learning and remembering the differences between them, and knowing they are NOT interchangeable.
